shutil.copy2仅复制一个文件并停止，而不是从循环复制整个文件

import shutil
import os

# 假设我们有一个源文件列表
source_files = ['file1.txt', 'file2.txt', 'file3.txt']
# 目标目录
destination_dir = 'destination_folder'

# 确保目标目录存在
if not os.path.exists(destination_dir):
    os.makedirs(destination_dir)

# 循环复制每个文件
for file_name in source_files:
    src_file_path = os.path.join('source_folder', file_name)
    dst_file_path = os.path.join(destination_dir, file_name)
    try:
        shutil.copy2(src_file_path, dst_file_path)
        print(f'Copied {src_file_path} to {dst_file_path}')
    except Exception as e:
        print(f'Failed to copy {src_file_path}: {e}')
